LIV – High-power Laser Diode Assembly

The laser diode is one of the most common devices used throughout photonics. The micro-assembly process calls for the placement and bonding of single or multiple laser diodes (stacked or complete bars), the placement, active alignment and bonding of necessary micro-optical components, device testing, and ultimately packaging and quality control.

ficonTEC’s machines and modules are capable of all the steps necessary for assembling laser diodes, even high-power devices.


Key features

  • Pick-&-Place and assembly of laser diodes as single emitters or as complete stack of laser diode bars

  • Bonding via eutectic soldering, epoxy adhesives, or laser-induced soldering

  • Placement, alignment and bonding of associated micro-optical components (fast-axis and slow-axis collimation)

  • Pig-tailing of output fibers

  • LIV testing and beam characterization

  • Full packaging assembly
